In Sweden Novembenfi, 1934 p I Claims. (Cl. 220-98) This invention relates to equipment for collectcharge. The bin is further provided with a lid I6 ing refuse and the like and more particularly to hinged to the pivotl5 which is mounted in a refuse collecting carts and also to dust bins conclamp or support l4, and the lid is adapted to be structed preferably for dustless discharge of the engagedv by a tongue 20 for 'connection'with the 5 bins into the carts and having means by which cover-plate when this is swung inwards. The 5 they are coupled together during the discharge hook I3 is pivotally supported by means of a pin operation. I! on a flange or flanges l8 secured to the trap 3.

The angle-iron II has position. The dust bin or can 8 is provided with such a form that its both flanges form an obtusetwo handles 9 located at some distance from each angle whereby the outstanding flange forms an 45 other on the same level but only one of them acute angle with the side-wall of the bin.
